autohell regression fix

[miodvallat]

Short description

I couldn't help but notice, while configuring recursordist, the shell complaining:

...
checking for the Boost context library... (cached) yes
./configure: line 23134: ]: command not found
checking whether to enable unit test building... yes
...

This was obviously caused by an extra ], the difficult part of figuring where.
It turns out this buglet was introduced in 6a590a16a8d82ea486684ea32318f043e143f176 last september.

Nice finding!

I didn't find anything - the shell did.
